umm so genital electrolysis questions...

I'm looking into srs and I am seeing that as requirements for some places. I've seen some places recommend using products like the One Touch at home if uncomfortable with showing anyone your genitalia while they um electrolysis you >.> I kinda wanted some real people's advice and wisdom on this since I'm new to the subject. Also mtf if that makes any of the info different. My main questions: -Is there anything like that at home I can do for it? -How painful and how long (i know it's multiple sessions so total hours please) is genital electrolysis if done professionally? Also what are the costs like? -Is it better to get it? (I'm pretty sure the answer is yes but hearing it from the voice of reason always helps) -Any other helpful tips you might be able to give on the subject? (this is my first post here so I hope it's okay)
